At that mileage and your described driving habit, I wouldn't worry about it one bit.
I currently have:
- 09 370Z - 6MT 35k miles
- 10 G37S - 7AT 52k miles
- 11 FX50 - 7AT 72k miles
So I have two cars that have the VQ37, and two cars that have the same 7AT. All have Akebonos. The only two "problems" I've ever gotten were busted diff bushing on the G (known problem with the liquid filled bushing), and fuel level sensor malfunctioning on the FX (another known problem), and neither were catastrophic nor complicated/expensive to fix.
